Alpha Platinum Aluminium

Boost148/110

Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 at the back lets you run wider tyres and a larger chain ring without affecting q-factor and pedalling efficiency.

Motor Armor

This unique protection shield made of lightweight but robust aluminium protects the motor against stones.

Rack mounts

Going for a long ride? Rack mounts make carrying accessories a breeze.

Bosch PowerPack 500

The premium Bosch lithium-ion battery features 500 Wh and a guaranteed long lifespan. The battery not only ensures long distances, but is also easy to remove and take with you.

Bosch Purion Display

Bosch's Purion display features a fully-functional speedometer with a backlit display, service interval indicator and battery range indicator. Its thoughtful design allows riders to scroll through functions or choose the right level of support while maintaining contact with the handlebars.

Bosch Performance CX

Bosch’s Performance CX line is made for rugged off-road use with a maximum torque of up to 75 newton metres, sustained power into the high cadence range for sporty acceleration and a sleek mid-mount motor for ideal weight balance and obstacle clearance.
